4D Flow Assessment of Vorticity in Right Ventricular Diastolic Dysfunction.

Bioengineering (Basel, Switzerland)

Browning JR, Hertzberg JR, Schroeder JD, Fenster BE.
PMID: 28952510
Bioengineering (Basel). 2017 Apr 05;4(2). doi: 10.3390/bioengineering4020030.

Diastolic dysfunction, a leading cause of heart failure in the US, is a complex pathology which manifests morphological and hemodynamic changes in the heart and circulatory system. Recent advances in time-resolved phase-contrast cardiac magnetic resonance imaging (4D Flow) have...

Oncotarget. 2017 May 23;8(39):64932-64953. doi: 10.18632/oncotarget.18117. eCollection 2017 Sep 12.

Glioblastoma (GBM) stem cells (GSCs) reside in both hypoxic and vascular microenvironments within tumors. The molecular mechanisms that allow GSCs to occupy such contrasting niches are not understood. We used patient-derived GBM cultures to identify GSC subtypes with differential...

Corolla chirality does not contribute to directed pollen movement in Hypericum perforatum (Hypericaceae): mirror image pinwheel flowers function as radially symmetric flowers in pollination.

Ecology and evolution

Diller C, Fenster CB.
PMID: 27547334
Ecol Evol. 2016 Jun 26;6(14):5076-86. doi: 10.1002/ece3.2268. eCollection 2016 Jul.

Corolla chirality, the pinwheel arrangement of petals within a flower, is found throughout the core eudicots. In 15 families, different chiral type flowers (i.e., right or left rotated corolla) exist on the same plant, and this condition is referred...

An Accurate In Vitro Model of the .

Angewandte Chemie (Weinheim an der Bergstrasse, Germany)

Clifton LA, Holt SA, Hughes AV, Daulton EL, Arunmanee W, Heinrich F, Khalid S, Jefferies D, Charlton TR, Webster JR, Kinane CJ, Lakey JH.
PMID: 27346898
Angew Chem Weinheim Bergstr Ger. 2015 Oct 05;127(41):12120-12123. doi: 10.1002/ange.201504287. Epub 2015 Sep 01.

Gram-negative bacteria are an increasingly serious source of antibiotic-resistant infections, partly owing to their characteristic protective envelope. This complex, 20 nm thick barrier includes a highly impermeable, asymmetric bilayer outer membrane (OM), which plays a pivotal role in resisting...

Three dimensional transrectal ultrasound imaging of the prostate: initial experience with an emerging technology.

The Canadian journal of urology

Chin JL, Downey DB, Elliot TL, Tong S, McLean CA, Fortier M, Fenster A.
PMID: 11178595
Can J Urol. 1999 Apr;6(2):720-726.

PURPOSE: A three-dimensional ultrasound system (3-D US) was evaluated for its clinical utility in transrectal prostate imaging, in comparison with the current standard 2-dimensional transrectal ultrasound (TRUS) imaging system. METHODS AND MATERIALS: The computer program developed in our laboratory...

Construction of azaspirocyclic ketones through alpha-hydroxyiminium ion or alpha-siloxy epoxide semipinacol rearrangements.

Organic letters

Fenster MD, Patrick BO, Dake GR.
PMID: 11418061
Org Lett. 2001 Jun 28;3(13):2109-12. doi: 10.1021/ol0160708.

[reaction: see text] Semipinacol-type rearrangements to produce azaspirocyclic ketones are presented. The yields and stereoselectivities of these reactions range from 67-94% yield and 2.8:1 to 1:0 diastereoselectivity, respectively.

Urinary retention in sexually abused women.

The Canadian journal of urology

Fenster H, Patterson B.
PMID: 12803708
Can J Urol. 1995 Dec;2(4):185-8.

Urinary retention is generally believed to be the result of neurogenic or non-neurogenic problems. In men, it is often caused by benign prostatic hypertrophy which can be treated by transurethral surgery.1 In women, however, studies have shown that urinary...

Observation of bose-einstein condensation in a dilute atomic vapor.

Science (New York, N.Y.)

Anderson MH, Ensher JR, Matthews MR, Wieman CE, Cornell EA.
PMID: 17789847
Science. 1995 Jul 14;269(5221):198-201. doi: 10.1126/science.269.5221.198.

A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled. The condensate fraction first appeared near a temperature of 170 nanokelvin and a number density of 2.5 x 10(12)...

Responsive brushes and gels as components of soft nanotechnology.

Faraday discussions

Ryan AJ, Crook CJ, Howse JR, Topham P, Jones AL, Geoghegan M, Parnell AJ, Ruiz-Pérez L, Martin SJ, Cadby A, Menelle A, Webster JR, Gleeson AJ, Bras W.
PMID: 15658767

Progress in the development of generic molecular devices based on responsive polymers is discussed. Characterisation of specially synthesised polyelectrolyte gels, "grafted from" brushes and triblock copolymers is reported. A Landolt pH-oscillator, based on bromate/ sulfite/ferrocyanide, with a room temperature...

Neutron reflection from the liquid-liquid interface: adsorption of hexadecylphosphorylcholine to the hexadecane-aqueous solution interface.

Langmuir : the ACS journal of surfaces and colloids

Zarbakhsh A, Querol A, Bowers J, Yaseen M, Lu JR, Webster JR.
PMID: 16316104
Langmuir. 2005 Dec 06;21(25):11704-9. doi: 10.1021/la0518086.

Adsorption of water-soluble, zwitterionic n-hexadecylphosphorylcholine (C(16)PC) amphiphiles has been examined at the hexadecane-aqueous solution interface using neutron reflectivity (NR) and interfacial tension measurements. The results of both methods indicate that the limiting area per surfactant molecule at the interface...

Fluorosurfactants at structural extremes: adsorption and aggregation.
